BINDING nnvron I BALING- rnnss'ns.

Application filed March 31, 1523'. serial No. 629,183.-

To all whom it may concern. v

Be it known that I, GUs'rAv RnU'rnR, a German citizen, residing at Munich, in Germany, have invented new and useful I m provem'ents in Binding Devices in Baling Presses, of which the following is a specification.

According to this invention the clamp r'etaining the forward end of the string is ar ranged with independent spring or other adjusting means and separate from the clamp for the rear end of the string. It is also desirable, consideringthe extensive application of the binding device in connectionjwith various makes and strength of string, that the clamp for the rear end of the string should also be spring adjusting and movably arranged.

The invention is relatively enlarged by the use of a rotatably mounted gripper-disk which is given a to and fro motion and has two teeth, each for a particular end of the string, which cooperate with the usual articulated adjustable clamping-cheeks on the binder frame.

This construction enables the binding device to be operated by only two mechanisms, namely one for the knotter and one for the gripper-disk. In this limitation of mechanism the invention resembles aknown binding device which latter, however, provides a single clamp for both ends of the string and thus has the objection that the forward end of string cannot yield at the baling and knotting operations and must be cut off so that considerable loss is caused in material.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1, is a front elevation of the stringing device; Fig. 2, a section on 2-2 of Fig. 1; Fig. 3, a section on 33 of Fig. 1; Fig. 4 is a sectional detail; and Figs. 5, 6 and 7, show various operative positions in connection with Fig. 3.

Fig. 8, is a transverse section on line 88 of Fig. 1. I

The driving pulley a mounted on the frame a: of the binder, is formed with a toothed ring a which through the intervention of a bevel wheel imparts motion to the knotter I) mounted in the frame as. The pulley a is formed with a guide-groove a for imparting to and fro motion to a gripperdisc 7' and to a sublocated ejector a. These two parts are mounted on a shaft 10 j0urnalled in the frai'ne x and having at its upper end an actuating arm o engaged in said groove a. The upper rim of the gripperdisc f is formed with a tooth e which acts in conjunction with a clamping-cheek 2" so as to retain the forward end 03 of-the binding string. The clamping-cheek c' is secured to the frame 00 on a pin 0 and is adjustably ar ranged for any required clamping pressure by means of a spring-pressed adjusting device. A second tooth p on the gripper-disc f helps to retain the rear end at of the string whilst being raised by the needle Z. The corresponding clamping-cheek g hangs movably on the pin 1 of the frame 00, and its clamping pressure can be regulated by means of the spring-pressed adjusting device h The gripper-disc f has on its periphery a tappet s for intermittent lifting of the clampingcheek 2' so as to release the end d of the string. is the guide for the string and is fast on the frame 00, the arm 70 being the active guiding member and thesho'r't arm carrying a knife 1" for cutting the rear end at of string raised by the needle Z.

In order to clearly explain the operation of the improved device it is advisable to ob serve first the operative positions of the parts shown in the Figs. 1 and 3. The for ward end Z of the string is herefirml'y retained between the tooth e of the gripperdisc 7 and the clamping-cheek z' and passes over the edge 70 of the string-guide is, then over the knotter I) through the opening of the ejector t and is slung over the lower side of the material being bound up. Having attained the required size of bale, the automatic starting of the binding mechanism 7 takes place in the known manner so as to sling the string over the open upper side of the bale and to knot the string. Figs. 1 and 3 show the position of the needle Z at the moment of placing the rear end at of the string fully around the bale. The needle by its further forward movement brings the rear end m of the string upon the kno'tter 6 between the teeth 0 and 39, after which it assumes the position shown in Figs. 5 and 6. Now, the driving pulley a turning anticlockwise, imparts, by its teetha, rotation to the knotter Z) in the direction indicated by the arrow in Fig. 5; the full rotation of the knotter effecting the knotting of the string. Shortly after starting the knotter b, the groove u swings the gripper-disc 7 in the direction of the arrow in Fig. 5 so that by reason of the adjustable springpressed clamping-cheek i, the end d of the string can yield to the pull of the knotter and can be drawn out ior the "formation of the knot. The final release advantageously efiected quickly through the intervention of the tappet s which at the proper moment slightly lifts the clampingcheek z'. The end m of the string, during the aforesaid turning motion of the gripperdisc, is placed in the spring-pressed adjustable clamping-cheek g and held fast by the tooth 3).

Whilst the string m is thus drawn into the clamp g, p, by the turning of the gripper-disc, .it is also brought in front of the knife 7" by the tappet s to be severed after the formation of the knot, which. latter is then taken off the knotter by the ejector Z), Fig. 6.

Hereon, the needle Z moves back and draws the string crosswise, for the preliminary laying of same, between the teeth 19 and 6 over the knotter I) so as to form the open loop for the next bale. As the needle draws back, the gripper-disc f turns clockwise back to its initial position, so that the tappet s releases the clamping-cheek i and the end m of the string is placed in the clamping device 6, 2', while at the same time the clamping device 79, g releases the string, thus setting the parts ready for renewed operation as in Fig. 3.

The clamping pressure of the cheek 1? should preferably be so adjusted as to avoid injurious stretching of string and to enable the latter to yield during the operation of binding and knottin The invention is suitable for application on presses for straw and similar materials, as also for application to mowing machines andit may be arranged for the use of string or wire.

I claim 1. In a binding device for baling presses having a separate clamping portion for each end of the binding string, means for drawing said string, a knotting device, and two separately mounted clamps connected with said knotting device for retaining the forward and rearward ends of said string.

2. In a binding device for baling presses having a separate clamping portion ior each end of the binding string, swinging jaws for drawing the string, vertically swinging clamping-cheeks and co-acting horizontally swinging teeth for retaining separate portions of string and producing an intervening crossed-over portion of string, a horizontally turning gripper-disc between said clamping-cheeks, and a tappet on the periphery of the gripper-disc for lifting said clamping-cheeks.

3. In a binding device for baling presses having a separate clamping portion for each end of the binding string, aws for drawing the strin hinged vertical clampingcheeks, a toothed gripperdisk turning between the clamping-cheeks, a tappet on said disk for lifting said cheeks, whereby a crossed-over portion of the string is drawn on said disk and retained between said cheeks and gripper-teeth, a U-shaped string guide and combined cutter, and an ejector for the knotted portion of the strin GUSTAV REUTER.
